How to concatenate an array with the same keys but different values?-CodePudding

I have two arrays, with the same keys, but there are two different values, they are city and quantity. How can I combine everything into one? i have this

$arr1 = array(
    [0] => Array
        (
            [article] =>  А6-01-05
            [name] => Example
            [price] => 9 700
            [quantity] => 3
            [brand] => Oktan
            [code] => УТ-00024246
            [city] => Nur-Sultan
        )
      )
$arr2 = array(
    [0] => Array
        (
            [article] =>  А6-01-05
            [name] => Example
            [price] => 9 700

I just write a simple code that can merge them as your needs, please take a try this:

<?php

$arr1 = array(
    0 => array
    (
        "article" => "А6-01-05",
        "name" => "Example",
        "price" => 9700,
        "quantity" => 3,
        "brand" => "Oktan",
        "code" => "УТ-00024246",
        "city" => "Nur-Sultan",
    )
);

$arr2 = array(
    0 => array
    (
        "article" => "А6-01-05",
        "name" => "Example",
        "price" => 9700,
        "quantity" => 5,
        "brand" => "Oktan",
        "code" => "УТ-00024246",
        "city" => "Almaty"
    )
);

$result = [];

foreach ($arr1 as $k => $item) {
    $result[$k] = $item;

    if (!isset($arr2[$k])) {
        continue;
    }

    foreach ($arr2[$k] as $k2 => $v) {
        if (!isset($result[$k][$k2])) {
            $result[$k][$k2] = $v;
            continue;
        }

        if ($result[$k][$k2] === $v) {
            continue;
        }

        for ($i = 2; $i < PHP_INT_MAX; $i  ) {
            if (!isset($result[$k][$k2 . $i])) {
                break;
            }
        }

        $result[$k][$k2 . $i] = $v;
    }
    
    ksort($result[$k]);
}

var_dump($result);
